PLASMA PARAMETER SLIDE RULE

A slide rule has been developed to facilitate rapid calculation of basic plasma parameters such as electron number density, Debye length, and the number of particles in a Debye sphere. These parameters can be readily calculated within an accuracy of 1.5% for most practical situations involving the application of plasma probes. In addition the slide rule can be used to determine whether Coulomb collisions preclude application of collisionless probe theory in plasma diagnostics. © 1969 The American Institute of Physics.
